Ok so working on the "only dumb question is the one not asked" I have a 2000 Winnebago Journey 36G. (I say have but its 600 miles north of me and will be till at least Christmas).

Does any one know where I would find the mattress dimensions of the queen bed in the rear sleeping quarters? My wife and I are thinking we will probably spring for a new mattress as neither of us is keen on second hand.

BTW what is DW I see it in a lot of posts and I assume its "other half", "Co-Pilot", "Spousey person" but cant work it out. I am sure it will be a DUH moment when someone tells me!

Hi Thanks for that. I had found the brochure online and unfortunately it just says Serta Mattress innersping no helpful info on actual size. One of the RV's we looked at had a queen RV that was queen width but shorter. I am hoping that the journey has a full length bed (else I will be hanging off the end!)

Cost-effective solution--buy a memory foam mattress topper from Costco. If you have a short queen , you may need to cut 5-6" off one end. Jim said it was super-easy to do. He used a fillet knife with an 8" blade & it "cut like butter".

I'd recommend you get an actual measurement of the space available for a mattress before buying. We found that our queen could be replaced by a king so we put a king tempurpedic that only overhangs a couple inches on each side and sleeps great!
